The show cdp neighbor command on Cisco devices displays various pieces of information about directly connected neighboring devices that support Cisco Discovery Protocol (CDP). Two key pieces of information displayed by this command are the platform of the neighboring device, which indicates the hardware type, and the device ID, which is typically the hostname of the device1. The command does not display the uptime or the Cisco IOS Software version; these details can be seen with the show cdp neighbor detail command. The IP address is also part of the detailed information and not displayed in the standard show cdp neighbor output1.
